New battery, now no headlight!

I replaced the aftermarket sealed battery with a new manufacturers suggested wet cell battery in my 2005 (27k miles) because the old battery wouldn't hold a charge. Perhaps R/R or stater problem but haven't tested them yet. New battery installed, runs fine but now I don't have any power to headlight. Must have knocked something loose. Checked every connection I can easily reach. Considering new LED headlight anyway if it's a light problem. Anyhow, scrolling through some threads here revealed typical problems with connectors and boxes, etc. Getting multi-tester soon to check wiring but until then....what can I focus on without wasting too much time/money?

Have you done any wiring mods? IE, the RLU wiring mod? If so, could you have possibly knocked the wire/jumper loose?

Check the fuses first.

Check the charging volts, if the stator isn't charging, it may not be tripping the headlight relay.

Fuses are good. Headlight worked before replacing battery. I haven't done any wiring mods but that doesn't mean previous owner didn't. Everything "looks" stock to me.

You do know the headlight only comes on after the bike has started?

Does the highbeam work?

You can test the headlight by running some wires direct from the battery, or at least use a voltmeter or circuit tester to see if it's getting power.

Also not sure why you'd replace a sealed battery with a wet cell...the exact opposite of what we recommend here.

Yes, I know headlight is supposed to come on after starting bike. I took advice from the local Kawasaki dealer on the battery. I've never done anything like this before (forums or modifying a bike), trying to learn some stuff here. If I can figure out how, I'll post some before/after pics of my bike so you can see what I'm going for.

Do the "blue wire mod" to see if that will bring your headlight back. You can do it in a temporary fashion by just interlocking the two spade receptacles together. Do your running lights come on?
